We report on highly phase sensitive measurements with a slightly detuned excitation of a quantum mechanical two-level system. It is formed by the single exciton ground state of a single quantum dot, which is incorporated in a n-i-Schottky diode. We excited the two-level system by two partly overlapping laser pulses with variable phase shift. To investigate the properties of the quantum system we determine its occupancy by measuring the photocurrent. The experimental data is compared to a numerical simulation of the system.
